S Corp vs. Partnership: Which Is Better?

Introduction

When advising clients on entity choice, many practitioners reflexively lean toward the S corporation for its simplicity, single layer of taxation, and potential employment tax savings. But that is not always the right move. Whether advising a start-up, a professional services firm, or a real estate syndicate, it is crucial to understand when a partnership may offer greater advantages, and fewer pitfalls, than its S corporation counterpart.

This post compares S corporations and partnerships across a spectrum of tax and legal issues, with an eye toward risks, tax savings, and strategic structuring considerations.

Background and Legal Framework

Under Subchapter S of the Internal Revenue Code, an S corporation is a small business corporation that elects pass-through taxation under IRC §1361 and meets stringent eligibility requirements under §1362. Only certain domestic corporations with a single class of stock and no more than 100 eligible shareholders may elect S status. By contrast, partnerships are governed by Subchapter K of the Code (§701 et seq.) and offer far more flexibility in ownership structure, profit and loss allocation, and distribution rights.

For many clients, especially those anticipating complex capital structures or disproportionate economic arrangements, the rigidity of S corporation requirements rules it out as an option. Recent developments, including the advent of the qualified income deduction, and IRS scrutiny of reasonable compensation in S corporations, have changed the cost-benefit calculus. Let’s look at some of the key issues you may want to consider.

1. Allocation of Income and Losses

• S Corporations: S corporations must allocate income, loss, and distributions strictly pro rata based on stock ownership, per IRC §1371(c)(1).
• Partnerships: Partnerships may allocate items of income, gain, loss, deduction, and credit in a manner that reflects the partners’ economic arrangement, subject to substantial economic effect under Reg. §1.704-1(b). This allows for special allocations, targeted distributions, and sophisticated profit-sharing agreements.

2. Employment Taxes and Compensation

• S Corporations: Shareholder-employees must receive reasonable compensation subject to employment taxes. Dividends distributed in excess of reasonable salary escape payroll tax, making this a commonly cited tax advantage. However, the IRS has stepped up enforcement in this area, challenging inadequate compensation as a tax avoidance scheme. Another negative is that a salary (subject to employment tax) can still be required if the business operates at a loss.
• Partnerships: General partners are subject to self-employment tax on their distributive share of income, while limited partners may be exempt under certain circumstances. Planning can help minimize SE tax exposure. And see below for comments on which may result in the lowest total tax liability.

3. Reorganization Flexibility and IRC §311(b)

• S Corporations: Under IRC §311(b), if an S corporation distributes appreciated property to its shareholders, it must recognize gain as if the property were sold at fair market value. This rule applies even to internal reorganizations or redemptions. As a result, restructuring or modifying an S corporation’s ownership or asset base can trigger unintended taxable gain, complicating exit planning or capital restructuring.
• Partnerships: Partnerships are generally not subject to a counterpart of IRC §311(b), which allows for more flexible and often tax-free contributions, distributions, and reorganizations under IRC §721 and §731. For example, a partnership can admit a new partner with minimal tax consequence by issuing a profits interest. This reorganization-friendly treatment often makes partnerships preferred for entities anticipating future restructuring, asset sales, or new partners.

4. Ownership and Capital Structure

• S Corporations: S corporations are limited to 100 shareholders, all of whom must be U.S. individuals, certain trusts, or estates. No nonresident aliens, partnerships, or other corporations may own shares. And only one class of stock is allowed, prohibiting preferred equity or differential distribution rights.
• Partnerships: Partnerships have no limit on the number or type of partners. Partnerships can issue multiple classes of equity with custom economic terms, making them ideal for joint ventures, investment funds, or businesses anticipating variable capital infusions.

5. Total Tax Liability Considerations

Beyond legal structure and compliance, evaluating which entity choice produces the lowest overall tax burden is essential. While S corporations can present a lower self-employment (SECA) tax liability due to dividend treatment of excess earnings, partnerships can yield a lower total tax liability, particularly for taxpayers eligible for the IRC §199A deduction for qualified business income (QBI) and who are already at the SECA / FICA wage base limits from other income sources.

Careful modeling and sensitivity analysis are crucial, particularly for clients near QBI phaseouts or with multiple income streams.

Conclusion

S corporations remain valuable, especially for closely held operating businesses with straightforward ownership. However, they are not a one-size-fits-all solution. Practitioners must carefully consider each client’s facts, long-term goals, overall tax burden, and potential exit scenarios before recommending an entity structure.

Key takeaways:

• Use S corporations for simple ownership structures and employment tax planning in certain situations.
• Use partnerships for flexible capital arrangements, special allocations, and investor-driven businesses.
• Watch for IRS enforcement trends around reasonable compensation.
• Model both structures to determine which yields the lowest overall tax burden, especially when factoring in Section 199A eligibility.
• Consider IRC §311(b) implications when evaluating future reorganizations or ownership changes.

We advise reviewing existing S corporation structures for potential conversion, particularly where growth plans or investor onboarding may clash with eligibility rules.
